RETAINER FOR TERMINAL S'JDAVES 0F WIRE BOUND BARRELS.

Specification of Letters Patent.

Patented Jan. 14, 1919.

Application filed November 24, 1917. Serial No. 203,718.

To all whom it may concern:

Be it known that T,- EDWARD W. ROBINSON, a citizen of the United States,residing in Savannah, Georgia, have invented certain Improvements inRetainers for Terminal Staves of l/Vire-Bound Barrels, of which thefollowing is a specification.

My invention relates to that method of manufacturing wire bound barrelsin which a set of staves is first confined between inner and outerbinding wires crossed or twisted between the successive staves of theset and in which the terminal staves of the set are then jammed togetherand held in such close relation, my invention consisting of a simple andefiective device for effecting such retention of the terminal staves.

In the accompanying drawings Figure l is a perspective View of a staveretainer constructed in accordance with my invention;

Fig. 2 is a transverse section through portions of the terminal staveswith the retainer in place thereon;

Fig. 3 is a face view of the staves and retainer shown in Fig. 2, and

Fig. 4 is a transverse section on the line 4-4, Fig. 3.

All of the views are on an enlarged scale.

Tn Figs. 2 and 3 of the drawing 1, 1, represent the terminal staves ofthe set, 2 the binding wires, and 3 the twisted ends of said bindingwires, beyond the terminal staves. When the terminal staves are jammedtogether these twisted portions of the wires are embedded in the edgesof the staves, as shown in Fig. 2, but in order to maintain the set ofstaves in barrel form it is necessary to retain said terminal staves insuch abutting relation to one another, and, with this object in view, myimproved retainer consists of a metallic sheet or plate comprisingopposite fiat edge members 5-5,

for bearing against the outer faces of the terminal staves on oppositesides of the outer binding wires, these edge members being connected byan arched central member 6 which bridges said outer wires, as shown inFig. 4:.

At each end of each of the side members 5 of the retainer is an inwardlyprojecting pointed tooth 7, and, when the retainer is driven into placeon the outside of the terminal staves 1, these teeth penetrate thestaves, as shown in Fig. 2.

The teeth 7 are considerably longer than the thickness of the stave, andwhen the retainer is being applied to the staves the latter aresupported upon a suitable anvil which contacts with the points of theteeth 7 when the latter pass through the staves and thus causes theteeth to turn outwardly so as to bite into the inner faces of the staves1, as also shown in Fig. 2.

Not only does the retainer thus serve to firmly hold the terminal stavesin their proper abutting relation but said retainer is so firmly securedto the staves that loosening or displacement of the same is likewiseefiectually prevented.

The side members 5 of the retainer are not in line with one anotherlaterally, hence the teeth 7 at each end of the retainer are indilferent transverse planes and the risk of splitting the stave whensaid teeth are driven into the same is thereby reduced to a minimum.

I claim:

The combination of the terminal staves and inner and outer wires of awire-bound barrel, the terminal ends of said wires being united to eachother between the terminal staves, and a retainer comprising an archedcentral member for bridging the outer binding wires, and opposite flatedge members, one on each side of said arched central member for bearingagainst the outer face of the terminal staves, each of said membersbeing of a length suiiicient to overlap the terminal staves on theopposite sides of the joint between them, and the end portions of theedge members being tapered to a point and bent down at a right angle soas to form pointed teeth in difiierent lateral planes from the centralarched member of the retainer, which teeth are driven into the terminalstaves.

In testimony whereof, I have signed my name to this specification.

EDWARD WILLIAM ROBINSON.
